Sorry I did not make myself completely clear, these disks mount with the 
wrong permissions, my user in this case uid 1000 has no access to the 
directory structure of the DVD, either a filemanager or cd in a console 
gets permission denied. All other DVDs I create from other recorders 
will mount with uid 1000 having read access to the directory structure.
